 Do I have to put my hand up to ask questions in class? Yes. Just don't put your hand up and ask to go to the bathroom. Yeah, you can just go. Just go. Do you have to put your hand up or do you yell at the person's name? I mean, you don't have to. You can just shout it in class if you want it to. Don't be that guy that just yells out at the lecturer. I don't know if you're meant to, but I just ask. Okay, so I still do that because that's me, but you don't have to. Normally they're willing to have these interactive classes. They really want students to engage with what they're teaching, so it's not kind of a one-way thing.
